• Witch hazel, horsetail, and Scots pine extract:  The manufacturer of Metanail refers to these three ingredients as the “Powerhouse Trio,” designed to eliminate fungal nail infections. The three nutrients are rich in multiple polyphenols and antioxidants. They work by eliminating toxins and free radicals that damage nails  . The three nutrients also soothe nails and skin and increase blood flow.
• Glycerin:  Many beauty products and serums contain glycerin because of its moisturizing properties. Metanail is no exception. The nutrient works by moisturizing the outer layer of the skin and the cuticles of the nails. It can prevent nails from weakening and splitting. Additionally, it can improve blood flow under the nails, thus increasing nutrient intake. 
• Rosemary and Pelargonium Graveolens: Rosemary and geranium are herbal extracts that moisturize your nails and skin. The duo can improve the texture and appearance of your nails. Additionally, manufacturer Metanail claims they can nourish your skin and strengthen your cuticles. 
• Gotu Kola:  The creator of Metanail Serum claims that Gotu Kola can prevent toxins from destroying nails. The nutrient forms a protective barrier that prevents toxins and microbes from entering the skin and nails. 
• Vitamins C and E: Both vitamins are rich in antioxidants and are therefore common in most skin repair and immune-boosting products. Vitamins C and E are abundant in most fruits and vegetables. The manufacturer of Metanail claims that the duo can promote healthy inflammation in the body and aid in the elimination of toxins. Additionally, a combination of vitamins C and E can increase collagen synthesis. The compound is necessary for strengthening hair follicles, skin, and nails. Likewise, collagen gives nails their shape, strength, and smooth texture.
• Lemon Peel and Aloe Vera:  Aloe vera and lemon peel extract are dense in a specific protein, 14 kDa, designed to rejuvenate nail health.  The specific protein strengthens nail cuticles  . Additionally, lemon peel and aloe vera accelerate healing, reinforce nail integrity and support growth. 
• Hyaluronic acid:  Hyaluronic acid is an anti-aging ingredient that can improve skin health and prevent brittle nails. Hyaluronic acid is commonly found in most skin serums due to its moisturizing effects. It can improve water retention and give nails a resilient appearance. 
• MSM: This is a strengthening component of Metanail Serum Pro. It can prevent nails from becoming brittle and split. MSM strengthens joint health and can slow the aging process. Studies show that it can prevent the appearance of fine lines and wrinkles.
• Jojoba Seed Oil and Sage Leaf Extract:  Jojoba seed oil and sage leaf provide your nails and skin with antioxidant and anti-inflammatory nutrients. The duo can soothe and strengthen your nails. Plus, they can both prevent your nails and skin from drying out too much. 
• Organic Green Tea and Hops:  The Metanail Serum Pro formulator refers to the green tea and hops blend as “true superheroes” that support skin and nail health. Green tea is rich in EGCG, and hops have several antioxidants to improve skin health and fight nail infections. 

Regular application of the serum can provide users with multiple health benefits. All of Metanail’s ingredients are curated in a Colorado-based facility that complies with GMP and FDA manufacturing principles. The nutrients are all safe and within acceptable dosages.
